CVE-2021-38899

Sensitive-information disclosure via shared connection credentials

Published Sep 20, 2021 · Updated Sep 16, 2024

Information disclosure in IBM Cloud Pak for Data 2.5 allows local users with special privileges to obtain highly sensitive data. The shared-connection feature makes common credentials available to authorized users instead of preserving individual credential attribution. Exploitation requires local access and special privileges; the exposed credential enables access through its associated connection and obscures attribution.
